Outline of Final Research Achievements

In the common marmoset, the problems associated with aging such as jaw and cranium, periodontal tissue, jaw movement, chewing / swallowing, respiratory function, etc. were clarified. Then, the utility of common marmoset as a human elderly model was evaluated. Three-dimensional X-ray motion pictures (cineradiograph) were taken with the elderly common marmosets in unconstrained state, and comparative analyzes of functions such as jaw movement, chewing / swallowing, respiration were conducted with reference to juvenile controls. In results, anatomical and functional changes was confirmed, and metagenome analysis of oral bacterial flora, bacteria common to humans and marmosets and the species-specific bacteria were clarified. Changes in the oral flora with aging were also observed. Common marmoset was confirmed to be highly useful as an oral disease model of human elderly.
